da /0101407270712 M UNITED STATES PATENT OFFICE.-

JOHN B'. GABRIELSON, or SPRINGVILLE, NEW YORK.

of New York, have invented certain new and useful Improvements in Radiators, of wlnch the followlng, taken in connectlon with the accompanying drawings, is a specification. n

The invention relates to radiators for motor driven vehicles; and the object of the 1m-' core construction in which the thin sheet metal which forms the walls of the zigzag water ways iscorrugated between contactingpoints in order to stiffen and strengthen the same thereby enabling the use of extremely thin sheet metal such as copper; and secondly, to provide alternate zigzag narrow spacing strips between the corrugated sheet cross corrugated between contacting points 'provement is, first, to provide a radiator to stiffen said strips, thereby providing a larger circulation of air and radiating surface within the radiator core and. around said zigzag water ways to aid in cooling the water; and the invention consists in the nwel features and combinations hereinafter set forth and claimed.

one of the double corrugated spacing strips.

Fig. 4 is a perspective view of one of the corrugated metal sheets formlng one of the sides of the spaced waterways; and Fig. 5

is a perspective view of one of the-double -corrugated spacing strips. "Like characters of reference refer to cor responding parts in the several views.

The numeral 10 designates the radiator core which is c p of Zigzag'sheet metal water ways 11 which extend from top tO'bOl':

. tom of said radiator core and are composed of oppositely placed sheets 12 which have the crosswise corrugations 13 therein from edge to edge of said strips, the central portion 14 being bent sufliciently sidewise in opposite directions to form the opening 15for RADIATOR.

Application filed March 27, 1918. Serial No. 224,938.

the zigzag water way 11; Edge portions 16 of the contacting sheets 12 each side of the opening 15 fit firmly against one another so as to be firmly-attachedto one another by solderingon both the inner and outer edges of the zigzag strips 12.

' The zigzag water ways 11 are spaced from one another'by means of the zlgzag strips 17 which are preferably somewhat wider than the contacting edge portions 16 of the strips 12 so as to brace the water way i 11 firmly and at the same time provide larger circulation of air between said water ways and a larger amount of radiating surface, at the same time saving an appreciable quantity of the costly sheet copper in said spacing strip; that is, if said spacing strip were to extend from the front to the rear edges of said core. The spacing strips 17 are made in zigzag form the same as the sheets 12 of the water ways 11 and have the corrugations 18 therein corresponding 'to the corrugations 13 in the sheets 12 between i the contacting surfaces 19 of the sheets 12 and 20 of the strips 17.

The contacting surfaces another, the central portions of said contacting surfaces, 19 of the water ways 11 being exposed to theair in addition to the corrusgated sides between said contacting surfaces 19 are preferably made flat so as .to brace firmly'against one- The spacing strips 17 also have grooves or I corrugations 21 crosswise of the corrugated side 18 between the flat contacting surfaces 20 to further stifi'en said strip 17 and also per by suitable dies which also form the sidewise bends 14 for the opening 15 of the water ways 11. The zigzag sheets 12 and zigzag spacing strips 17 are assembled in a suitable frame, which clamps the parts firmly in the assembled form, sothat the contacting edges 16 and portions of the strips 17 may be dipped in the solder flux thereby rigidly attaching all the parts to one another in the desired position ready forinsertion in a suitable casing;

I clainf as new z-e Y In a radiator core, pairs of zigaag sheets having horizontal flat .parts and having The corrugations 13, 18 I "other half of hexagonal air cells, the other their edge portions contacting and secured together, the divergent parts of said edge portions of the sheets being formed with nesting longitudinal corrugations, and zigzag spacing strips of slightly greater Width than the lengths of said contacting edge portions ,of the'pairs of sheets having corresponding fiat parts'seated upon the respective fiat parts of one of the sheets and extending over and beyond the inner ends of said contacting portions,the pairs of sheets forming one half and the spacing strips the sheet of each pair being bent outwardly from points between the front and rear edges of the spacing strips to form Water ways, the divergent parts of the spacing strips being formed With longitudinal and with centrally transverse corrugations.

In testimony whereof I have affixed my 20 signature in the presence-of two Witnesses.
